HOT-WATER HEATER.

SPECIFICATION forming part of Letters Fatent No. 648,946, dated May 8,1900. Application filed September 15,1899. Serial No. 730,644. (Nomodel.)

To all whom it 17mg concern.-

Be it known that I, FREDRIOK Gunrnnaa citizen of the United States,residing at Kewanee, in the county of Henry and State of Illinois, haveinvented certain new and useful Improvements in Hot-Water Heaters, ofwhich the following is a specification.

My invention relates to certain new and useful improvements in hot-waterheaters; and its primary object is to construct the heater in a novelmanner to secure a better circulation of heat and a greater area ofheating-surface for the boiler than has been possible in heaters of thischaracter heretofore constructed.

Another object of the invention is to provide an improved boiler forhot-water heaters of such a character that the heat may act on bothsides thereof and raise the temperature of the water quickly.

Another important object of the invention is to provide a hot-waterheater of simple construction which can be built inexpensively and whichwill give far superior results to the heaters now in general use.

My invention has other objects in view, which will be fully and clearlypointed out hereinafter and specifically described in connection withthe accompanying drawings, in which- Figure 1 is a side elevationshowing a heater embodying my invention. Fig. 2 is an end elevation.Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 1. Fig. 4is a transverse sectional view on the line 4 4 of Fig. 6, showing theheater mounted in a suitable casing. Fig. 5 is a longitudinal sectionalView on the line 5 5 of Fig. 2. Fig. 6 is a longitudinal sectional viewon the line 6 6 of Fig. 7, suitably arranged in a brick casing. Fig. 7is a front view of my improved heater,

' showing the doors and front plate thereof.

Fig. 8 is a cross-sectional view showing a modification of my invention.

Referring to the drawings, in which like letters of reference denotecorresponding parts in all of the figures, A designates the fire-box,and B grate-bars of any suitable de scription, said grate-bars beingsupported on the frame 0, which in turn is mounted on the legs D, asshown in Fig. 3, or on the brick foundation E. (Shown in Fig. 4.) Theboiler is arranged above and around the fire-box, and it is of a novelconstruction, comprising two sections F and G. The lower section F ismade in two parts, each comprising a rectangular body supported on theframe of the heater at each side of the fire-box and throughout thelength of the heater. The upper section of the boiler is constructed inthe form of an arch, which is supported above the firebox in such amanner that its lower edges will be separated from the lower section ofthe'boiler a suitable distance, thereby providing an opening between thetwo sections of the boiler through which the heated air may pass toradiate above and around the outer side of the boiler. The arch G of theboiler is connected with the lower sections of the boiler by means of Ythe vertical tubes H, so that the air may circulate through the upperand lower sections of the boiler.

Air is admitted to the boiler through the supply-pipe I, which isconnected with the lower part of one end of the boiler, as shown in Fig.5,and the heated water escapes from the boilerthroughthehot-waterpipesJ,thesmokeflue K being provided on one sideof the heat radiating surfaceL. In order that the heated air may be directed to circulate over thegreatest possible area of the boiler, I provide the plate M on the outersideof the boiler to close the space between the arch and the lowersection on that side of the boiler adjacent to the smoke-flue, so thatthe air will circulate through the open space N between the arch and thelower section of the boiler on the right-hand side and around the outersurface of the boiler in the space L. By this means I provide a largearea of circulation for the hot air, during which it is always incontact with the boiler, and the boiler is of such a construction thatthe water will be quickly heated.

In Figs. 1 and 4 I have illustrated my invention showing the boilersupported on legs D, and in Figs. 4 and 6 I have shown the boilermounted on a suitable foundation and inclosed within a casing.

In Fig. 8 I have shown a supplemental arch G, located above the arch Gof the boiler, which is employed when it is desired to increase thecapacity of the heater, said supplemental arch being supported above thearch G and connected with the hot water pipe J, so that the water maypass from the arch G into the arch G and thence through hot-water pipeJ. This arrangement of the supplemental arch provides an additionalcirculating-space L between the two arches, the plate M being extendedup to join the two arches together at one side, and thereby form asingle side wall for the circulatingspace L.

It will not be necessary to enter into a detailed description of themanner in which my heater may be incased and supported, as a great manychanges may be made therein without in any way departing from the spiritor sacrificing the advantages of the invention.

The operation of the improved heater will be readily understood, it isbelieved, from the foregoing description. The heated air passes from thefire-box through the side opening between the arch and the lower sectionof the boiler and through the openings P in the arch and circulatesaround on the outer side of the boiler, the said boiler being of suchconstruction that the heat will act on the water instantly and raise thetemperature quickly.

Having thus fully described my invention, What I claim, and desire tosecure by Letters Patent, is

1. In a hot-water heater, a boiler consisting of a lower sectioncomprising compartments arranged on opposite sides of the fire-box, andan upper arched section supported above said compartments and separatedtherefrom to form spaces through which the heat may circulate to passabove and around the boiler; and pipe connections at intervals betweenthe upper and lower sections.

2. In a hot-water heater, a boiler comprising a lower section consistingof two rectangular compartments arranged at opposite sides of thefire-box, and an upper arched section supported above the lower sectionand separated therefrom to form circulatingspaces, and pipe connectionsat intervals between the upper section and the compartments comprisingthe lower section.

3. In a hot-water heater, a boiler comprising a lower section and anupper arched section supported above the lower section and connectedtherewith at intervals, a circulating'space between the upper and lowersections of the boiler and a plate inelosing the circulating-space onone side of the boiler, substantially as described.

4. In a hot-water heater, the combination with a fire-box of a boilercomprising two sec tions, the lower section consisting of two10ngitudinal parts arranged on each side of the fire-box, and an upperarched section supported above the lower section and connected therewithat intervals, a supply-pipe communicating with the lower section of theboiler, exit-pipes leading from the upper portion of the arched sectionof the boiler and a plate secured on one side of the boiler to close thespace between the upper and lower sections of the boiler on that side,substantially as described.

5. In a hot-water heater, a boiler comprising a lower section, an upperarched section supported above the lower section and connectedtherewith, a supplemental section arranged above the arched section andconnected therewith and a plate secured on one side of the boiler forclosing the circulating-space between the upper and lower sections atthat side, substantially as described.
